MEANS FOR ATTACHING HEELS.

re m- Specification of Letters Patent atented May 29, 1917.

Application filed March 29, 1916. Serial No. 87,651.

lie it known that l. An'rur'n J. W'IIJLS, ot' lro ltlield. in the county of 'orcester and State of Massachusetts, a citizen'of thc l'nited States. have invented a new and useful Improvement in Means for Attaching lleels, of which the following is a specification.

Rubber heels for th attachment of which my invention is particularly intended, are usually made with nail recesses extending into the heel a short distance from its wearing surface, eaeh reinforced at its bottom by a metal washer, which is moldedinto the heel at the time the heel is vulcanized, and.

should be parallel with the upp and under There is always some dillieulty in properly locating these washers in the body of the heel during the molding and vulcanizing process as they are apt to be displaced in the mold as theplastic rubber is forced around them. Nloreover, the cost of the washers and labor of installing them is considerable. The purposeof these washers is to hold the nailhead from pullthe shoe, serving as a reinforcement to the head of the nail.

My invention comprises a mode of attachment as well as a new heel, the heel having .no washer in it and the head of the nail, which is my invention, being of a character to spread and serve the purpose of the washer heretofore use: a

My invention will be understood by reference to the drawings, in which it is shown in its preferred form.

Figure 1 is an enlarged elevation of a nail embodying my invention,

Fig. 3 being a top view thereof,

Fig. I) an elevation showing'the condition of the nail h ad after the nail has, been driven,

Fig. 4 being a top view thereof.

Fig. 5 shows the preferred heel construction to be used with my nail, the nail being in position to be driven into the recess.

Fig. (i shows the first position of the nail head within the'recess,

Fig. 7 being its second position. and

Fig. 8 showing the na-il,-the heel and the shoe in final position, these last three views illustrating the cooperation of the recess with the nail head in the process of driving.

Fig. 5 is a nail embodying my. invention -whieh has but a single prong.

is theshank of the nail, B being the head. Preferably integral with the head are. as shown, three PIOJOttlOlis b which when the nail is first made project down; ward and are bent slightly outward as at Z),

all as shown in Fig. l and Fig. i, which is a top vi -v thereof. 3 is the heel which has a recess a ha ring preferably a center depression (1', therein, the purpose of which is tonail is still further driven down it takes the position shown in Fig;- 7 where it will be noted that the ends 72 of the projections Z), because of their outwaLilly-projecting char: acter, have been turned outwardly by the bottom of the recess 0 and have been flattcned out more or less so that they are driven into the rubber. and in their final position, asshownin Fig. 8, they project upward, being bent duringthe further process of driving. ln-praetiee these nails are driven by a maehii I and at one blow or by pressure, the above views being illustrative merely of the operation of the parts of the nail.- in Fig. S it-wil'l also be noted that the tip a of the nail has been-clenched into the shoe in the manner usual, so that in this case the shoe and the heel are gripped together by the. clenching point of the nail which engages the inner surface of the shoe, and the projec ions 7! which form part of the head.

so that they are firmly held without any reasonable possibility of being torn apart.

I do not mean to limit myself to a nail head having-the precise number of projections shown as one or more may be used to accom 'ilish the desired-result (see-Fig. 9

-" where one projection b is shown). -My nail accomplishes by itself what has heretofore been tlCCOl'DPliSllOtl by nail and a washer embedded in and forming part of the heel. The. projections, if not a part of the nail head, should be made of reasonably'fi; ible material so that they ma ;;"perform the bendiug function which is necessary to ll'ltlkG them bend properly as shown. In using the term shoe 1 mean to include. the leather heel or sole or any part to which the rubber heel may be attached. I use the term "rubber heel by way of illustration as my nail may be used for other purposes than heel attaching, and other rubber or plastic articles may be applied by it.

\Vhat I claim is l. The nail above described having a head with one or more flexible prongs extending downwardly therefrom the ends of said prongs projecting outwardly.

The nail above described having a head with one or more flexible prongs extending downwardly therefrom, the ends of said piongs projecting outwardly, in combination with an article having a recess the lower surface of which is adapted to engage the outwar ll \'-projeeting ends of said prongs and llatten them out, whereby they will be driven laterally into said article when the nail is driven therethrough.

$5. in combination, a rubber heel, a shoe, and a nail passing through said heel and into said shoe, and clenched at its point, said nail having a head with prongs projecting at right anglesthereto into the interior of said heel, whereby said heel will be attached to said shoe by said prongs and said clenched point.
